Urgent advice needed

[fishorfishin]

I currently have had the following list of fish, problem free for about 6 months.

Queen trigger
Blue line trigger
Queen angel
Emperor angel
Porcupine puffer
Foxface
Snowflake eel
Doctor tang
Sailfin tang
Parrot fish and a hamlet


All were doing very well, and this past week I lost the hamlet, parrot fish and I have porcupine puffer in hospital tank currently (not looking good)

It all happened within 5 days, no new additions.
.the porcupine puffer has two cloudy eyes and loss of appetite. My emperor angel currently has one cloudy eye, almost looks to be peeling.

The only thing that has changed with tank as from what o can see is the tank went from 80-81 up to 85. It's in my basement, and we have had a bit of a hit save.

No inverts or corals, just fish, and there dropping like flies.

Any guesses?

What size tank are they in? Queen and bluelines are both extremely aggressive. Could they be ganging up on your other fish?

 

[fishorfishin]

No, highly doubtful. No real aggression, I view tank 3-4 hours a day, everyone.minds there own.

I put prazi in, if that don't clear it up, my approach will be to let things.play out
